If you’re planning to use epoxy resin for your next project, chances are you’ll also need to apply it over an existing surface.
And that might mean wood. In this post, we’ll look at common questions about whether epoxy can be applied over stained wood, and what happens if you don’t take proper precautions when using your adhesive over an old coat of polyurethane.
Will epoxy stick to stained wood?
Epoxy is a liquid that can be applied over any surface. It is the strongest adhesive on the market, so yes, epoxy can stick to stained wood.
Epoxy does not work like other adhesives because it’s a two-part resin, meaning you need to mix two liquids as opposed to one solid like super glue or hot glue.
The second part of this mixture includes a catalyst that makes sure your epoxy cures properly and sticks together while curing at room temperature for 24 hours and hardens within 48 hours.

How do you apply epoxy over oil-based stain?
The key to applying epoxy over oil-based stain is to make sure the surface of your wood is clean before you start. The most common way to do this is with a rag, liquid soap, and warm water.
You’ll also want to make sure that your wood is dry before applying the epoxy.
The next important step is applying epoxy in thin layers rather than in one thick layer. A good way to do this is with a paintbrush—just make sure it has soft bristles so they don’t scrape off any of your stains while you’re painting on the epoxy!
Finally, don’t apply too much epoxy at once; instead, work in small sections so you can spread it evenly across as much of your furniture as possible without wasting any materials or having any spills on the floor (which would be bad).
What kind of stain can you use under epoxy?
You can use any type of stain underneath the epoxy. You will want to avoid oil-based stains, as they can cause bubbling in the finish.
Most stains that you would use on a wood floor should be fine for your project. The only thing we recommend is that you test the stain first before committing it to your entire project, just to make sure it won’t react with the epoxy or create blotches in the finish.
Can you pour epoxy over wood?
You can pour epoxy over wood. It’s a good idea to sand the surface area with 80-grit sandpaper before you apply the epoxy so that any blemishes in the wood will be smoothed out.
Epoxy is a great choice for outdoor furniture and other outdoor projects because it’s waterproof and resistant to water damage.
If you’re applying epoxy on an outdoor piece of furniture, make sure it’s well-ventilated as it cures because epoxy can give off toxic fumes during this process!
What happens if you use epoxy over oil based stain?
If you use epoxy over a polyurethane finish, it will not stick. The reason for this is that oil-based polyurethane is a solvent-type finish that contains chemicals that will dissolve the epoxy.
Epoxies are water-based so they do not react well with solvents.
Polyurethane is more difficult to sand off than stain because of its thickness and durability, but it does have some advantages over stain in terms of ease of application and longevity.
If you want to apply epoxy over an existing polyurethane finish, however, then there’s no problem at all—the two materials are compatible with one another!
Do you need to seal wood before epoxy?
If you want to apply epoxy to a previously stained surface, you’ll need to remove the old finish. There are several ways of doing this:
- Use a sanding sponge to rub off the stain. This will work on varnish and lacquer finishes but not oil-based stains or paints. If you don’t have access to a sanding sponge, use steel wool instead; just be sure not to rub too hard or you may scratch the surface!
- Clean off any remaining residue with an all-purpose cleaner like Murphy Oil Soap (or any other brand) after sanding down your piece of furniture. Then wipe it down with paper towels before moving on with the rest of your project.
How do you prepare wood for epoxy resin?
Epoxy resin is a two-part adhesive that hardens when you mix the two components. It’s often used to adhere wood or other materials to each other, and it can also be used to glue on top of existing surfaces.
To apply epoxy resin, you must first clean the surface of your wood thoroughly with soap and water. The goal is to remove any oil from your hands or tools that might interfere with adhesion later.
Next, apply epoxy resin using whatever method best suits your project: roller, brush, putty knife, or paintbrush.
Will epoxy stick to oil based polyurethane?
No, it won’t. Epoxy does not stick to oil-based polyurethanes. The only way to apply epoxy over an existing finish is to sand the old finish off and resand the wood before you apply your new epoxy.
If you’re wondering whether epoxy is compatible with stained wood, the answer is a resounding yes! Epoxy resin is one of the best ways to seal and protect your project from damage caused by moisture, chemicals, or sunlight.
In fact, it can even be used as a finish in its own right if you want something glossy and hardwearing.
However, before deciding on this type of coating for your next project make sure that all surfaces are clean and dry so as not to interfere with curing time or cause other problems down the line.
